The HTML markup produced by this template includes an hCard microformat, which makes the place-name and location parsable by computers, either acting automatically to catalogue articles across Wikipedia, or via a browser tool operated by a person, to (for example) add the subject to an address book. Within the hCard is a Geo microformat, which additionally makes the coordinates (latitude & longitude) parsable, so that they can be, say, looked up on a map, or downloaded to a GPS unit. For more information about the use of microformats on Wikipedia, please see the microformat project.
